Abstract

PURPOSE:To reduce considerably the labor required for program generation by adding a classifying device and an indirect/direct converter and providing a function which can process not only working programs of a direct designation form but also working programs of an indirect designation form. CONSTITUTION:Working programs are inputted to an input device 2 in a form of a paper tape 1 or the like and are stored in a memory A 3a. Working programs stored in this memory A 3a are classified to programs of the direct designation form and those of the indirect designation form by a classifying device 6. Programs of the indirect designation form are converted to programs of the direct designation form by an indirec/direct converter 7. Working programs of the direct designation form are stored in a memory B 3b and are given to an operation processing device 4. Devices 6 and 7 can be constituted by incorporating private hardware or can be processed with software by microcomputers.

作を制御する。An example of the configuration of a conventional device will be described with reference to FIG. A processing program in the form of a paper tape 1 or the like is input to an input device. Here, one movement command of a machine tool always requires coordinate data of an end point, and the command methods include an absolute command (absolute value command) and an incremental command (difference value command). The machining program inputted to the input device is stored in the memory 3, and sequentially processed by the arithmetic processing device. The arithmetic processing unit d controls the operation of the servo device j based on operation commands obtained by arithmetic processing of the machining program.
